摘　　要：目的:总结目前常用中文言语测试材料在语后聋人工耳蜗植入者言语识别上的效果。方法:采用临床常用的中文言语测试材料,对32例语后聋人工耳蜗植入者进行安静条件下单音节字、扬扬格词、中文BKB语句、中文HINT语句识别率以及嘈杂噪声下HOPE语句识别阈的测试,分析比较各类测试材料在语后聋人工耳蜗植入者康复成效评价时的临床适用性。结果:语后聋人工耳蜗植入者在安静条件下扬扬格词表、中文BKB句表和中文HINT句表的识别率达到100%的人数分别为1人、14人和4人;同时,高分数段(≥85%)人数分别为17人、26人和14人,均呈现出不同程度的天花板效应。反之,安静条件下单音节字识别率满分为0人,高分数段人数为6人;噪声下HOPE句表识别阈测试不受天花板效应干扰。结论:对于相当一部分语后聋患者,现有的中文言语测试材料已出现不同程度的天花板效应。安静条件下单音节字识别率和噪声下HOPE句表识别阈测试更能相对客观地评价患者的言语识别能力。Objective：To evaluate and compare outcomes effects of Chinese recognition materials in post-lingually deafened patients with cochlear implant.Method：Thirty-two post-lingually deafened cochlear implant users participated in the study.Each one of them was given a series of speech recognition tests including the speech recognition score of monosyllable words,spondee words,Chinese BKB sentences and MHINT in quiet,as well as speech recognition threshold of HOPE corpus in babble noise.Speech recognition scores and thresholds were compared among these test materials using histograms,scatter diagrams and statistical methods.Result：Recognition scores for spondee words,Chinese BKB sentences and MHINT were affected by ceiling effects,with 1,14 and 4cases scored 100% respectivelty.Meanwhile,17,26 and 14cases scored more than 85%correspondingly.On the other hand,speech recognition scores for monosyllable words in quiet and speech recognition threshold for HOPE corpus in babble noise were not affected.Conclusion：For a considerable part of post-lingually deafened patients using cochlear implant,some Chinese speech recognition materials have demonstrated different degrees of ceiling effects.While speech recognition scores for monosyllable words in quiet and recognition threshold for HOPE corpus in noise can evaluate the performance of speech recognition abilitymore objectively.
